"He is very forgiving," Kim Crumpler, animal operations manager at the Montgomery Humane Society, said, of the adorable puppy.

"He really is just a sweetheart," she added later.

Tank is spending his days at the Montgomery Humane Society, but goes home in the evening with Crumpler. She said he loves being around humans and interacting with other dogs and cats.

Authorities say Tank suffered loosened teeth, a broken leg in two places and a head injury at the hands of his owner, Michael Harper.

Harper is accused of beating, kicking and throwing the black-and-white puppy for having an accident in his Cherry Street home on June 19. He was arrested and charged with aggravated cruelty to animals. Harper's bond was set at $15,000.

Crumpler said a neighbor reported the abuse. When humane society officers found Tank, he was unconscious, but thankfully he doesn't seem to have suffered any permanent injuries from the head trauma.

His caretaker said Tank hasn't regained the energy of regular puppy, but he waddles as best he can with his cast before tiring out.

"Right now, he is very laid back and easy to please," Crumpler said, adding that he mostly wants to cuddle.

But, there is one puppy – or dog for that matter -- characteristic that hasn't been affected by the injuries.

"Even with the stitches in his tongue, he is a bottomless pit," Crumpler said. "He eats and eats and eats."

Tank's leg is expected to be healed in about six weeks, and he will be placed into a foster home soon. A foster family who is likely to adopt is preferred. Anyone interested will have to go through an application process.
